D. Abstract New spectra have been obtained of the magnetic Ap star 53 Cam, well spaced through its 8.03 day rotation period, covering the spectral regions λλ3900 - 3960 and 4250 - 4315. These data, and previously obtained Hβ Zeeman analyzer observations of the longitudinal field strength, have been used to derive models of the magnetic field geometry and the abundance distributions of Ca, Cr, Fe, Sr, and Ti. The models have been obtained by use of a new line synthesis program that incorporates the effects of an assumed magnetic field and abundance distribution into the calculation of line profiles. Calculated profiles are compared with observations. The model is used to derive a radius of R/R_sun; = 2.3±0.4, a luminosity of log L/L_sun; = 1.4±0.17, and a mass of M/M_sun; = 2.0±0.3 for 53 Cam.
