The level structure of P/sup 29/ was investigated with the reaction Si/ sup 28/(p, gamma )P/sup 29/ for proton energies between 0.3 and 2.3 Mev. Levels of P/sup 2>/ at 3.09, 4.34, and 4.76 Mev were excited with (p, gamma ) resonances at proton energies of 0.371, 1.65, and 2.09 Mev, respectively. The strength of a gamma resonance expected for excitation of a 3.49 Mev level in P/sup 29/ was derived to be less than 5 x 10/sup -4/ ev. This low value is attributed to K- forbiddenness of the gamma decay of this level. Gamma rays from the 0.371 Mev resonance lead to levels at 1.95 and 1.37 Mev; those from the 1.65 Mev resonance lead to the ground state and, rather weakly, to the 1.37 Mev state; gamma rays from the 2.09 Mev resonance lead to the ground state only. Angular distributions are in agreement with the following spin assignments for the levels of P/sup 29/: 1.37 Mev (3/2), 1.95 Mev (5/2), 3.09 Mev (5/2),; 4.34 Mev (3/2), and 4.76 Mev (1/ 2). The excited states found in these experiments are assigned to rotational bands based on Nilsson orbits 8, 9, 10, 11, and 16. (auth)
