Abstract

Gamma-ray spectra of a 20-h {sup 255}Fm source containing -1 mCi activity were measured with a 25% Ge detector and a low-energy photon spectrometer (LEPS). Gamma lines with intensities as low at 1.0 x 10{sup -6}% per {sup 255}Fm {alpha} decay were observed. Gamma-gamma coincidence spectra of a {sup 255}Fm sample were measured with the GAMMASPHERE array. A comparison of the {gamma}-ray spectrum gated by the Cf K{sub {alpha}} x-ray peak with the {gamma}-singles spectrum provided spins of the excited states in {sup 251}Cf. The {gamma}-ray data, in conjunction with previously measured {sup 250}Cf(d,p) reaction data, allowed us to characterize several single-particle and vibrational states above the N=152 subshell gap.

Energy levels of {sup 251}Cf populated in the {alpha} decay of {sub 100}{sup 255}Fm and EC decay of {sub 99}{sup 251}Es

Journal Article Ahmad, I; Greene, J; Moore, E; ... - Physical Review. C, Nuclear Physics

Gamma-ray singles spectra of extremely pure (chemically and isotopically) samples of {sup 255}Fm, with strengths of {approx}1 mCi, have been measured with a high-resolution 2-cm{sup 2}x10-mm germanium LEPS detector and with a 25% Ge spectrometer. Gamma rays with intensities as low as 1.0x10{sup -6}% per {sup 255}Fm {alpha} decay have been identified. The electron spectrum of a mass-separated {sup 251}Es source was measured with a cooled Si(Li) electron spectrometer. The spectrum provided the conversion coefficients of low-energy transitions in {sup 251}Cf and thereby their multipolarities. The present measurements confirm the previous assignments of single-particle states in {sup 251}Cf. These includemore »« less

Neutron one-quasiparticle states in {sup 251}Fm{sub 151} populated via the {alpha} decay of {sup 255}No

Journal Article Asai, M; Tsukada, K; Ishii, Y; ... - Physical Review. C, Nuclear Physics

Excited states in {sup 251}Fm populated via the {alpha} decay of {sup 255}No are studied in detail through {alpha}-{gamma} coincidence and {alpha} fine-structure measurements. Five excited states reported previously in {sup 251}Fm are firmly established through the {alpha}-{gamma} coincidence measurement, and rotational bands built on one-quasiparticle states are newly established through the {alpha} fine-structure measurement. Spin-parities and neutron configurations of the excited states in {sup 251}Fm as well as the ground state of {sup 255}No are definitely identified on the basis of deduced internal conversion coefficients, lifetimes of {gamma} transitions, rotational-band energies built on one-quasiparticle states, and hindrance factors ofmore »« less

Proton states in the Z = 99 nucleus /sup 251/Es excited by /sup 251/Fm electron capture decay and /sup 250/Cf(. cap alpha. ,t) reaction

Journal Article Ahmad, I; Sjoblom, R; Friedman, A; ... - Phys. Rev., C; (United States)

Level structure of the Z = 99 nucleus, /sup 251/Es, has been investigated by measuring the ..gamma.. rays and conversion electrons associated with the electron capture decay of 5.3-h /sup 251/Fm, and from triton spectra produced in the /sup 250/Cf(..cap alpha..,t)/sup 251/Es reaction. The ..gamma..-ray spectra were measured with a 2-cm/sup 2/ x 5-mm planar and a 25-cm/sup 3/ coaxial Ge(Li) detector and the electron spectra were measured with a cooled Si(Li) detector. Forty-five ..gamma.. rays were identified in /sup 251/Es and the multipolarities of most of the transitions were deduced. Logft values for the observed electron capture transitions weremore »« less

Spectroscopic studies beyond the N=152 neutron gap: Decay of {sub 101}{sup 255}Md and {sub 101}{sup 256}Md

Journal Article Ahmad, I; Chasman, R; Fields, P - Physical Review. C, Nuclear Physics

The isotopes {sup 255}Md and {sup 256}Md were produced by the irradiation of {sup 253}Es with 35-45 MeV {alpha} particles by ({alpha},n) and ({alpha},2n) reactions and were removed from the target by a helium jet system. {alpha}, {gamma}, and {alpha}-{gamma} coincidence spectra were measured with Si and Ge(Li) detectors. From the EC decays of {sup 255}Md and {sup 256}Md, levels in {sup 255}Fm and {sup 256}Fm were deduced. Favored {alpha} decay of {sup 255}Md was found to populate the 7/2{sup -}[514] single-particle state in {sup 251}Es, thus establishing the 7/2{sup -}[514] as the {sup 255}Md ground state.
