Os188,190,192(t,p) reaction at 15 MeV

A study of the heavier osmium isotopes Os190, Os192, and Os194 has been made with the (t,p) reaction using a 15 MeV triton beam. The osmium nuclei may be considered as transitional nuclei going from a deformed to a spherical shape with increasing neutron number and the (t,p) reaction is used to probe this change. The study principally investigates the position and strength of the 0+ states, a number of new such states being observed. The nucleus Os194 is also reported in some detail for the first time with 15 excited levels observed and 7 spin assignments made. [NUCLEAR REACTIONS Os188,190,192(t,p), Et=15 MeV.
