Title: Correlation studies of the {sup 5}H spectrum

Abstract

The nuclear system {sup 5}H was studied using the {sup 3}H(t,p){sup 5}H transfer reaction at a laboratory energy of 57.7 MeV and small center of mass angles. The energy and angular correlations among the {sup 5}H decay fragments were obtained by complete kinematical reconstruction. A broad structure in the {sup 5}H missing mass spectrum above 2.5 MeV with a typical width of several MeV was identified as a mixture of 3/2{sup +} and 5/2{sup +} states. Analysis of interference patterns observed in the measured angular correlations disclosed the 1/2{sup +} ground state of {sup 5}H concealed in the smooth missing mass spectrum. The deduced values for the resonance energy and width are E{sub g.s.}{approx_equal}1.8 MeV and {gamma}{sub g.s.}{approx_equal}1.3 MeV. The estimated cross sections for population of the ground state and the doublet of excited states at {theta}{sub c.m.}=5 deg. are 150{+-}50 {mu}b/sr and 4.6{+-}2 mb/sr, respectively.
