Trying to solve a differential equation by these rows

(%i1) L:10e-3;C:50e-3;R:0.5;i0:2.074;v0:0.732;
(%i2) 'diff(i,t,2)+2*R*'diff(i,t)/L+i/(L*C)=0;
(%i3) ode2(%,i,t);
(%i4) ic2(%,t=0,i=i0,diff(i,t)=(v0-2*R*i0)/L);

How can I simplify the final coefficients  and exponent of the exponential
solution to get a form like this

i=a*%e^b+c*%e^d

Thanks a lot
Renzo
