The interacting boson model of Arima, Iachello and co-workers is applied to the even zinc isotopes 62Zn-72Zn. Two boson configurations are used to account for the behaviour of excited 0+ states; one is the usual particle boson configuration and the other a configuration representing excitation from the 56Ni core. The parameter variation in the model is constrained as much as possible to agree with calculations from a non-degenerate multi-shell fermion basis for the bosons. Energy levels, quadrupole moments and B(E2) values are calculated. Values obtained compare favourably with experiment and with other calculations.
