Abstract
Numerous studies have been done on the ⁵⁶Co nucleus which hasone proton less than the magic number 28 and one neutron in excess, to determine how closely the shell model predictions explain its behavior. The spins and parities of ⁵⁶Co excited states populated by ⁵⁶Ni decay have been interpreted in terms of one-particle-one-hole shell model configurations, then more recently the importance of two-particle-two-hole configurations have been demonstrated. The lifetimes of ⁵⁶Co excited states have been measured in this work by the delayed coincidence method to investigate whether two-particle-two-hole configurations result in some degree of deformation in this nucleus leading to a collective effect. The lifetime of only one state and upper limits for two others are previously known for this nucleus.
