yes in 1950s were some study about nuclear nuclear tank shells
but they stop somewere in 1960s, I don't know why
maybe because they need 5 kg (11 lb) of Californium-251 for mini nuke
and that Californium ist very rare and to expensive for massproduktion as tank shells
also the problem of save storage and radioactivity play a major role
in this point of view a Neutron bomb against divisions of Sovjet tanks makes more sense
a neutron bomb is small Nuke design with "lower" explosive energy.
but release a large portion of its energy as deathly neutron radiation
