Your pension is an asset of yours and will therefore be considered as part of the overall financial settlement. As would savings, investments, other property, art & stamp collections etc.
The CETV will likely indicate that the pension is to be relatively low in value (due to the time you contributed) even though it is still a defined benefit scheme. Whether she is entitled to any would depend on how you / the court decide to split your assets between you. Depending on your situation, for example, you might have a claim on her pension.
If you can't reach an agreement over the financial side of things then the court will decide, but the duration of the relationship will usually be taken into account. In simplistic terms, a wife of over 40 years is likely going to have more claim over a rich husband's assets than one of 18 months...
By the way, it might be that the Scheme Trustees offer her a form of membership of the scheme based on a share of your accrued rights. No money actually changes hands, she just gets a tiny pension when she reaches the relevant age.
More importantly is going to be the need for you to re-join the scheme once the divorce is finalised. This is your future form of income and one that is incredibly valuable as it is designed to provide you with an index-linked income (ie it goes up every year) from age 60 onwards based on your earnings over the years. Restarting will give you the chance yo fill any gap made by the transfer.
You also need to re-think your death in service life assurance and complete a fresh nomination of benefits/expression of wish form if your ex-wife is currently named as beneficiary.
